Driving Dynamics Control (FDC with SMG - if equipped)
The MS45.1 ECM contains two different throttle progression functions (Sport and Normal). The FDC function is selected by pressing the "SPORT" button located in the center console (1).
When pressed, the button provides an input signal to the center console switch center (SZM). The signal is transmitted from the SZM via the K-CAN > SGM > PT-CAN to the ECM and the power steering.
This activates the sport characteristics for the Electronic throttle control (EDK). This provides an increase in throttle opening and response time over the non-sport position.
When this function is activated, "SPORT" appears in the LC display in the instrument cluster. When the ignition is cycled, this function resets back to the non-sport function (it must be re-selected by the driver).
